Wabco 4460970000 Temperature Sensor

Description

The Wabco 4460970000 Temperature Sensor is a critical component within engine management systems, responsible for accurately monitoring engine temperature. This sensor is commonly used in heavy-duty vehicles and industrial engines to provide essential data for optimal engine performance and emissions control. Measuring 150 x 167 x 22 mm, this device features a TYCO 108-18013-0 electrical connection and operates within a measuring range of -40°C to +125°C. Its OE specification ensures reliable performance and seamless integration, while the IP 6K9K protection class guarantees durability in harsh operating environments. The 10KΩ resistance value at 25°C contributes to precise temperature readings, enhancing overall engine efficiency and longevity.

Key Features & Benefits

This little guy measures the temperature of either the engine coolant or sometimes the intake air, depending on which one you need. It's a pretty simple job, really – it takes a temperature reading and sends that information as an electrical signal to the car’s computer, the ECU. That signal lets the computer know how warm or cold things are running. It’s a key piece in a lot of different systems. The ECU uses that temperature information to adjust things like the fuel mixture, ignition timing, and even whether the cooling fan kicks on. It's essential for keeping the engine running smoothly and efficiently. It also plays a role in things like your temperature gauge on the dashboard, and can even affect how the AC system works.

Symptoms, Risks & Replacements

If this sensor goes bad, things can get messy. You might notice your engine running poorly – maybe rough idling, trouble starting, or even a check engine light. Sometimes, you’ll notice if your temperature gauge is reading incorrectly, swinging wildly, or just staying stuck. More seriously, a faulty sensor can cause the engine to overheat or, conversely, run overly rich, potentially damaging the catalytic converter. It's one of those parts that doesn’t always give a huge, obvious sign it’s failing, but it’s crucial for preventing bigger problems down the road. We often have these in stock, and you can find a good selection at places like Fixparts Online if you prefer to look yourself. It’s a relatively inexpensive part to replace, but it can save you a lot of headaches.
